Harold and Kumar are two stoners who can't seem to get a break. Their last adventure found them traveling across country to find a White Castle hamburger in order to satisfy a weed-induced case of the munchies. This time, the boys get themselves in trouble trying to sneak a bong onboard a flight to Amsterdam. Now, being suspected of terrorism, they are forced to run from the law and try to find a way to prove their innocence. What follows is an irreverent and epic journey of deep thoughts, deeper inhaling and a wild trip around the world that is as "un-PC" as it gets.
